Quality Control

Our Soybean Oil, Polymer With Glycerol, Phthalic Anhydride And Styrene is manufactured under a rigorous quality management system. Each batch is tested against stringent in-house specifications to ensure consistent performance in your formulations. Key parameters such as acid value, viscosity, solids content, and color are monitored. Certificates of Analysis (COA) documenting these results are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and open flame. Recommended storage temperature is between 15°C and 25°C (59°F and 77°F). Keep away from strong acids and organic solvents. Under these conditions, the product is typically stable for 24 months from the date of manufacture.
